“…When living in contaminated environments or after an initial taste of metal-rich plant materials, insects develop an aversion and decrease ingestion rates [ 17 , 28 ]. In this study, as Cd concentration increased, food intake of adult sweet potato weevils decreased, which is consistent with previous reports.…”

“…According to Jiang et al [ 26 ], Cd stress increased the resistance of larch ( Larix olgensis ) seedlings to gypsy moth, with decreases in gypsy moth body weight and detoxification mechanisms associated with changes in contents or activities of protease inhibitors, tannins, and phenolic acids in L. olgensis seedling needles. For insects, heavy metals can be transferred to herbivorous insects through food chains, causing chronic toxicological effects on growth and physiology [ 27 ], altering behavior [ 28 ], and simplifying the community of plant-associated insects [ 6 , 29 ]. After an initial taste of metal-rich plant materials, the desert locust Schistocerca gregaria develops an aversion and decreases ingestion rates [ 30 ], whereas the grass miner Chromatomyia milii reduces feeding and oviposition on heavy metal-exposed plants [ 31 ].…”

The sweet potato weevil Cylas formicarius is a notorious underground pest in sweet potato (Ipomoea batatas L.). However, little is known about the effects of cadmium (Cd) stress on weevil biology and resistance to pesticides and biotic agents. Therefore, we fed sweet potato weevils with Cd-contaminated sweet potato and assessed adult food intake and survival and larval developmental duration and mortality rates, as well as resistance to the insecticide spinetoram and susceptibility to the entomopathogenic fungus Beauveria bassiana. With increasing Cd concentration, the number of adult weevil feeding holes, adult survival and life span, and larval developmental duration decreased significantly, whereas larval mortality rates increased significantly. However, at the lowest Cd concentration (30 mg/L), adult feeding was stimulated. Resistance of adult sweet potato weevils to spinetoram increased at low Cd concentration, whereas Cd contamination did not affect sensitivity to B. bassiana. Thus, Cd contamination affected sweet potato weevil biology and resistance, and further studies will investigate weevil Cd accumulation and detoxification mechanisms.

“…TA also demonstrates a comparable capability of chelating metals [ 61 ]. TA, degraded in the gut by bacteria and enzymes, is absorbed from the alimentary tract in animals, it is found in blood plasma [ 62 ] and can have a chelating effect on the toxic metals present in blood and internal organs [ 57 ]. Thus, TA is apparently one of the crucial components of tea determining the preventive effect of tea in relation to Cd and Pb.…”

“…Another study on rats showed that Pb was a metal more resistant than Cd to being bound by TA [ 30 ], where the use of TA solutions with the concentration from 0.5% to 2% in adult rats simultaneously exposed to Cd and Pb resulted in a statistically significant reduction of Cd absorption in brains but had no effect on the level of Pb. This could be due to the fact that Pb reveals a considerably stronger affinity with thiol groups [ 62 ], which do not occur in polyphenolic compounds, than with hydroxyl groups present therein. It is noticeable that the effectiveness of TA and teas in relation to Cd and Pb was higher in the second experimental period than in the first one.…”

The protective effect of tannic acid and tea solutions on the lungs, hearts and brains of adolescent Wistar rats exposed to Pb and Cd was studied. Metals were administered with feed (7 mg Cd and 50 mg Pb/kg). Two experiments were carried. Experiment 1 aimed to determine the level of tannic acid (TA), most effectively reducing the adverse impact of Pb and Cd on the organs of adolescent rats (aged 5 weeks, weighing 169.3 ± 14.7 g) during combined exposure. TA was administered with drink (0, 0.5, 1, 1.5, 2 or 2.5% solutions). In Experiment 2, adolescent rats (aged 6 weeks, weighing 210.6 ± 12.1 g) received an aqueous solutions of black, green, red or white teas. TA and teas had a positive effect on reducing the accumulation of Cd in the organs. The results obtained suggest that long-term continuing administration of TA increases its effectiveness as a chelator for Pb. A 2% TA and white tea solution proved to be the most effective. In the analyzed tissues, increased activity of SOD and CAT was recorded as a result of the use of the TA and teas; thus, they can efficiently prevent the prooxidant effect of toxic metals.

Many species of the Tephritidae family are invasive and cause huge damage to agriculture and horticulture, owing to their reproductive characteristics. In this review, we have summarized the existing studies on the reproductive behavior of Tephritidae, particularly those regarding the genes and external factors that are associated with courtship, mating, and oviposition. Furthermore, we outline the issues that still need to be addressed in fruit fly reproduction research. The review highlights the implications for understanding the reproductive behavior of fruit flies and discusses methods for their integrated management and biological control.This article is protected by copyright.
